Fagor FEB23E1B Air Pressure Switch - Huba Control 605.99667
Air pressure switch manufactured by Huba Control (series 605), installed in Fagor ECOCOMPACFE20E, FE24EC1N, and FEB23E1B boilers. It cuts off the ignition if it does not detect the correct flue gas draft. It is identified by the code Huba 605.99667, equivalent to the Fagor code N49G006M4. The replacement requires first confirming the fault of the part through technical diagnosis, even when the boiler does not ignite or is locked due to air pressure fault.

How to check if ref. N49G006M4 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference N49G006M4. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms that require diagnosis in the pressure switch N49G006M4
The pressure switch controls the air or water pressure to authorize operation. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler does not ignite: it stays in standby or tries to ignite without the flame appearing.
Cause: The air pressure switch does not close the contact because it does not detect the minimum draft depression, and without that signal, the control board does not allow the gas to open.
Make sure that the extractor starts and spins correctly before assuming that the pressure switch is faulty.
- 02
The boiler intermittently locks out: sometimes it starts up properly and other times it stops when trying to start.
Cause: A partially obstructed pressure port causes the pressure switch to receive an irregular signal and operate inconsistently.
Check the pressure connections and the silicone tubes of the pressure switch: make sure they are free of condensation, folds, or dirt.
- 03
The extractor works well but the burner never ignites.
Cause: Even if the fan is running, if the pressure switch does not close the contact, the control board understands that there is not enough draft and does not allow the gas to pass.
Check that the pressure switch activates when the fan starts (you usually hear a small click); if it doesn't activate, first check its tubes before the part itself.
Fagor fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| F-2 | The air pressure switch does not detect air circulation (or is defective) and the boiler locks out. | The air pressure switch does not close due to lack of depression/draught or internal fault; check continuity of the contact when the fan starts and measure depression in the tubes, as well as inspect for obstructions in intake/exhaust. |
These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
